Hello everyone! Patch 4.3 is out today. The ToC for this patch is:
## ToC: 40300
One of the big UI changes is that divide by 0 no longer works. Specifically, Blizzard's Lua fork no longer silently handles division by zero; it throws a Lua error now.
Have fun hacking away at your addons and I hope 4.3 goes smoothly for you all!
